LOUIS STOOKSTROM, OF ST. LOUIS, MISSOURI.

SELF-HEATING SAD-IRON.

SPECIFICATION forming part of Letters Patent No. 417,601, dated December 1'?, 1889.

Application filed July 31, 1889.

l scription, reference being had to the accom- Apanying drawings, forming part of this speciiication.

My invention relates to an improved sadiron; and it consists in features of novelty hereinafter fully described, and pointed out in the claim. y

Figure I is a side elevation of my improved iron. Fig. II is a vertical section. Fig. III is a transverse section taken on line III III, Fig. II.

1 represents the' body of the iron, provided with openings 2, through which the heat and the products of combustion are allowed to escape.

3 represents an oil-tank, supported on the body 1 by rings 4, screwed into the-body, as shownat 5, Fig. II. On the upper ends of the rings -I are extensions 6, for receiving a handle 7. I prefer to inclose the tank 3 in a jacket 8, of asbestus or other good non-conductor of heat. The cylinder is held from end movement within the rings by setscrews 9, passing through lugs 10 on the rings 4. The cylinder is provided with a filling-opening l1 and a discharge opening or port 12, with which communicates a pipe 1 3, by which the liquid is conveyed from the tank to a burner 13. The pipe 13 passes through the hollow body of the iron, as shown in Fig. II. Be- A neath the pipe 13 is a commingling--tube 14, into which the gas is discharged from the burner 13, as represented in Fig. II. The bottom of the commingling-tube is provided Serial No. 319,332. (No model.)

with a series of slots or openings 15, through -which the gas escapes into the hollow body of the iron, whereit is ignited and consumed. A transverse section of the commingling-tube and its supply-pipe is shown in Fig. III, the section being taken through one of the slots l5.

An iron thus constructed is cheap and du rable, and is Well suited to the purposes for which it is designed.

I prefer to locate the commingling-tube directly beneath the supply-pipe, as shown, so that the heat therefrom is utilized for heating the supply-pipe and generating the gas before the burner is reached. I also prefer to make the slots 15 transverse of the length of the commingling-tube, for the purpose of more effectually spreading the flame within the body of the iron.

The burner I3a is provided with a top plate or cap 13b, against which the flame impinges when the burner is first lighted, and which serves to assist in the vaporization before the jet or llame from the burner enters the tube 14 and heats the pipe 13.

The combination of the hollow body, a tank, rings by which the tank is secured to the body, and which are provided with a handle, lugs on the rings, set-screws passing through the lugs for holding the tank within the rings, a jacket surrounding the tank, a pipe communicating with the tank and passing through the body, a burner on the pipe, and a slotted commingling-tube located within the hollow body, substantially as and for the purpose set forth.
